摘　　要：提出了一种新的对象族模型,即陈述式对象族模型。定义了陈述式对象族模型,给出了模型的几何结构和拓扑结构,通过约束详细说明了特征的语义,以约束图的形式给出了该模型中特征的表示,给出了模型的语法描述。通过实例验证了模型的有效性,克服了传统的基于历程建模的不足,提高了CAD建模设计效率,降低了设计成本。A new family of object model,i.e.declarative family of object model,was imposed in this paper.The model was defined,geometric and topological structure of this model was presented,semantic of feature was specified by constraints,constraint graph was used to represent features in the model,grammar specification of model was provided.Validation of the model was verified in a instance,and insufficient of traditional procedural-based modeling was overcome,design efficiency of CAD modeling was developed,and design cost was reduced.
